Hello everybody,<br>
<br>
I recently started using Drools (with C#) and I have some problems in<br>
understanding how temporal operators work with the duration field. According<br>
to the documentation, the temporal operators work with startTimestamp and<br>
endTimestamp of events, the semantics being defined with inequalities. In<br>
order to work, temporal operator requires the duration field to be declared.<br>
Now the questions:<br>
1. What does @timeStamp stay for? The start or the end timestamp?<br>
2. Does Drools calculate startTimestamp and endTimestamp if I set @timeStamp<br>
and @duration attribute from my C# code? If not how can I set them? (like<br>
shall I declare like @startTimeStamp(sth) and set from the C# code?)<br>
3. Do temporal operators work if I do not set explicitly the start and end<br>
timestamps but just @timeStamp and @duration attributes?<br>
<br>
<br>
In particular, I have this drl file (%VAR% are replaced by other code):<br>
<br>
<br>
declare IntensionalEvent<br>
@role(event)<br>
@timeStamp(timeStamp)<br>
@duration(duration)<br>
end<br>
<br>
rule "Expression (%EVENTNAME1%, %OPERATOR%, %EVENTNAME2%, %TIMESPAN%,<br>
%TIMEVAR%)"<br>
dialect "mvel"<br>
when<br>
$eventA : IntensionalEvent( name == '%EVENTNAME2%' )<br>
$eventB : IntensionalEvent( this %OPERATOR% $eventA,<br>
name == '%EVENTNAME1%'<br>
) over window:time( %TIMESPAN% )<br>
<br>
then<br>
blah blah... create an IntensionalEvent and set timestamp<br>
and duration<br>
<br>
end<br>
<br>
Thanks everybody,<br>
Gil<br>
